COPYING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 314,091, dated March 17, 1885.

Application filed December 3l, 1883. (No model.)

To all whom it may concern.-

Beit known that I, SETE WHEELER, of the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Copying Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the drawings accompanying and forming part of this specication.

My improvements relate to a machine by means of which impressions maybe obtained on a continuous web or roll of paper, from which web or rollthe portions receiving the impressions are subsequently severed, or such portions may be severed immediately after the impressions are made. By reason of my 'improveniente perfectimpressions may be taken by hand-power to the extentof from one hundred to two hundred per minute.

In the drawings, Figure lis a side elevation of a machine in which are embodied my improvements, the impressions being received continuously on the surface of the paper as it is fed along from off its roll and before it is rewound on another roll. Fig. 2 is a front elevation thereof.

A' is the base-plate of the machine. B B are two standards, one at each end of the said base-plate A. Gis a receiving and impression roll journaled in the said standards.

D is a roll which is journaled in slotted projections E E on the standards for holding the roll or web of paper F which is to receive the impression. The openings E E of the standards serve to permit the journals of the roll D to rise therein-that is, recede from the center of the receiving and impression roll as the web is wound from off roll D onto roll C, and to have the surface of the paper constantly in contact with the periphery of said receiving and impression roll.

G is an absorbent roll, upon the periphery of which the original matter from lwhich the impression is to be taken is transferred. In order to permit the journals H H of this absorbent roll to rise so as to just keep the roll in contact with the surface of the paper as it is drawn from off the roll D onto the receiving-roll C, such journals are placed in slotted projections I I on the standards B B.

The receiving and impression roll G has atcached to one end of its shaft .I a crank-handle, K, by means of which motion can be given to such roll, and the paper F be thereby drawn from off the roll D and into contact with the periphery of the absorbent roll G, and after receiving impressions be wound continuously upon said roll C.

The base plate is hinged to a table or stand at L, by means of which the machine can be thrown back in the direction of the dotted line shown on Fig. l, so as to enable the paper wound upon the roll C to be withdrawn therefrom, as may be required.

lAt the front part of the base-plate A is a knife-bar, M, attached by means of two screws, N N, so as to leave a space between the inner surface of the knife-bar and the front edge of the base-plate, in order `that the end of the paper can be withdrawn through such space from the roll C, the knife-bar M severing the paper into the required size of sheets when pressed irmly against the lower edge.

The operation of the machine is as follows: The paper F passes from off the roll D onto the receiving and impression roll C, the absorbent `roll containing the original matter required to be impressed thereon moving iu frictional contact with roll C, and with each revolution makes an impression on such surface of the paper. As fast as it is made the paper F is wound onto the roll C, to be subsequently withdrawn therefrom and cut ofi by means of the knife-bar M.

The absorbent roll G may, instead of having a periphery of gelatine for the original matter, as in the hektograph apparatus, contain a stencil or other suitable surface of original matter.

I claim- 1. The combination of a roll containing a web of paper with an impression and storing roll on which said paper is run and stored after it has been impressed, and an absorbent roll in contact with the surface of such paper,

paper, and a knife-bar for severing the paper 1o into portions, such elements being arranged upon a base-plate which is hinged to a stand or table, substantially as described.

SETH WHEELER.
